GETTiNG STARTED:
Turn off the audio system. It is also advisable
to disconnect the negative () terminal of your
vehicles battery whenever performing
installation work.
Before cutting, drilling or inserting any screw, check
clearances on both sides of the planned mounting
surface. Also check for any potential obstacles, such
as window tracks and motors, wiring harnesses, etc.
Check both sides of the vehicle, many vehicles are
not symmetrical!
Always wear protective eyewear.
CROSSOVER NETWORK iNSTALLATiON:
The crossover networks supplied with your ZR
System should be installed in a dry location inside
your vehicle. DO NOT INSTALL THEM INSIDE OF
A DOOR! Doors often get wet on the inside, which
can damage your crossover networks and could
potentially damage your entire sound system. The
crossovers can be screwed into a solid surface via
two holes located under the protective cover of the
case. To access these holes, simply squeeze the sides
of the cover while gently pulling the cover away from
the base. Make sure that your mounting location will
not cause damage to wiring, fuel lines, brake lines or
any other vital component of your vehicle. Once you
have screwed the case in and made your connections,
snap the protective cover back into place.
! !
WARNiNG
! !
It is absolutely vital that your component system is
connected as shown in this manual. Failure to connect
the system as shown may result in damage to your
speakers which is NOT covered under warranty.

Do not substitute different crossover networks into
your ZR System. Do not use crossover networks
intended for different ZR models.
WiRiNG DiAGRAMS - STANDARD AND
Bi-AMP / Bi-WiRE METHODS:
The input to the crossover networks can be set
up in one of the following two ways:
Standard: This wiring configuration is used when
you wish to drive each crossover with a single
amplifier channel or pair of wires. In this mode, you
will only use the input connections marked INL+
and INLon the crossover circuit board (INH+
and INH are not used). Your crossovers are pre-
set in this mode at the factory. This mode is selected
by placing the pair of jumper bars shown in Diagram
A to the lower position marked "STD. Tweeter
(T+ and T) and woofer output connections
(W+ and W)are made as shown in Diagram A.
Bi-Wire (Bi-Amp): This position is selected by
placing the input mode selection jumper bars in the
upper position as shown in Diagram B. In this mode,
the inputs to the woofers low-pass filter and the
tweeters high-pass filter are electrically isolated. This
permits connection of different amplifier channels to
the woofer and tweeter sections (bi-amp), or separate
wire pairs for each section from a single amplifier
channel (bi-wire). In this mode, you will use the Input
connections marked INL+ and INL to drive the
low-pass woofer section of the crossover and INH+
and INH to drive the high-pass tweeter section of
the crossover. Tweeter (T+ and T) and woofer
output connections (W+ and W)are made as
shown in Diagram B.
Please note that the use of additional active
filtering for the woofer low-pass or tweeter high-
pass is not necessary or recommended in this
mode. The crossover network has been engineered
to shape the system response... additional filters
may degrade performance. JL AUDIO

CROSSOVER NETWORK ADjuSTMENT
The ZR crossover networks have been designed
to allow tonal adjustments to the upper midrange
response and tweeter level. These adjustments
make it possible to fine-tune your system to suit
your listening preferences and to compensate for
various speaker mounting applications.
ADjuSTABLE MiDRANGE PRESENCE:
Your ZR crossover networks provide a unique
midrange presence control, located under the
clear cover. The midrange presence is selectable
via a set of pins and allows for four settings. These
settings affect the amplitude of the upper midrange
response of the ZR component woofer. We
recommend that you begin your listening with the
factory setting (3) and adjust up or down as needed
to compensate for mounting location, orientation or
personal taste.
ADjuSTABLE TWEETER LEVEL:
ZR crossover networks also provide five levels
of tweeter adjustability designed to compensate for
different mounting locations, vehicle interiors and
personal taste. These levels are selectable via a set of
pins located under the clear cover of each crossover
case. We recommend that you begin listening in the
REF (Reference) position. To find the optimum
tonal balance in your installation, experiment with
alternate tweeter level settings by moving the jumper
connector. It is safe to switch jumpers while the
system is playing.

TWEETER PROTECTiON:
The ZR crossover networks are equipped with
an advanced electronic tweeter protection circuit
designed to minimize the possibility of tweeter failure.
This electronic device monitors current going to the
tweeter and
